    在你們生活的城市,環境空氣質量怎么樣,是清醒還是渾濁呢?這幾年,各城區的環保部門都在大力改善環境,建設大量的PM2.5監測站點,可是大家知道為什么要這么做嗎?下面就由藍月小編來給大家解答一下疑惑吧。


    PM2.5標準*早是在20世紀末開始使用的,原本是用于對工業排放進行監測的一個指標。由于PM2.5與人們的生活和健康密切相關,所以它很快就成為世界各國空氣質量監測的重要指標之一。



    PM2.5顆粒粒徑小、質量輕,能長時間滯留空氣中,并隨氣流發生水平和垂直運動。地基監測是獲取PM2.5濃度信息的主要手段,通過定點監測站點的精密儀器,可以快速、準確獲得PM2.5在不同時刻的濃度數值。由于PM2.5很容易受到地形、氣象要素、污染源等諸多因素的影響,具有復雜的時空分布特征,尤其是在城市里,不同的城市功能分區,不同的道路機動車流量,不同的工業布局和部門設置都具有不同的污染物排放特點。因此,單獨的地基監測站點對于PM2.5的監測來說,其測量數據只能代表該監測點PM2.5的情況。這是遠遠不夠的,更重要、更有效和更實際的,是要及時了解整個區域范圍內PM2.5的空間分布狀況。



    因此,為了對危害健康的PM2.5進行有效監測,需要建設一批散布在不同位置的地面監測站點,編織成一張 “大網”,及時掌握PM2.5的空間分布情況,并對可能造成的危害進行及時預警和干預。藍月測控出品的BM400-PM系列高精度空氣PM2.5、PM10檢測單元是專門針對潮濕多塵的環境,針對性設計的一款在線型空氣質量檢測儀器,在持續可靠工作方面具備顯著特點,具備極好環境耐受性。儀器檢測數據精準、濕度影響小、體積小巧。非常適用于學校、商場、醫院、樓宇、建筑工地、道路、隧道、堆料場、垃圾場、風景區、化工廠等場合實時在線監測等。
